A cycling friend of mine uses this light. I was impressed by its brightness and visibility from a long distance. I am a road cyclist and I feel a lot safer with this light on my bike. Drivers of motor vehicles can see this light from a long distance away giving them time to react to and adjust to sharing the road with a cyclist.

I ride mostly in the country and am concerned with that occasional vehicle that may ride up my back. Sometimes I have to ride in busier traffic. The flashing lights are an attention getter. I am hopeful it will alert the driver to my presence. Adds a level of peace of mind.

This is the brightest tail light I have encountered. On flash it is visible for a LONG ways. One set of batteries (AAA) last a whole season. Clips to the little loop on the back of my underseat bag, on the back of my helmet, on the back of my (Camelback) backpack. I have clipped it to the back of the neck of my shirt and on the back of the waste bands of my shorts. It never falls off. The frame mount is hard to use and adjust and does not detach quickly.

Great prouduct. Extremely visible even at great distances. I ride during early morning hours when it is dark. Cars find it easy to spot me. Battery life is great. I have used it for an entire year without having to change the battery. Easy to operate and to install. I like this light so much, I bought a second one for a second road bike. This light is very nice compliment to your high visibility gear when riding. I highly recommend this product.

absolutely love this light. I clip it onto my bag as my seatpost isn't long enough for seatpost attachment. I had the cherrybomb light before that I really liked, but this is 1 watt and really a nice light. get THIS one...thumbs up
